An ad hoc committee will plan and conduct a public workshop featuring presentations and discussion on how to develop partnerships with communities with the goal of improving population health. The workshop will 1) feature selected speakers from communities across the United States who have taken steps to improve the health of their communities, and 2) include discussion of the potential roles of communities for improving population health. The committee will identify specific topics to be addressed, develop the agenda, select and invite speakers and other participants, and moderate the discussions. An individually-authored summary of the presentations and discussions at the workshop will be prepared by a designated rapporteur in accordance with institutional guidelines.
